California State ADU Laws

California has some of the most progressive ADU legislation in the country. Recent laws including AB 68, SB 13, and AB 881 have significantly streamlined the ADU approval process and reduced barriers for homeowners.

Key California ADU Regulations:

• Size Limits: Detached ADUs can be up to 1,200 sq ft. Attached ADUs can be up to 50% of the primary dwelling or 1,200 sq ft, whichever is less.
• Setbacks: Minimum 4-foot side and rear setbacks for detached ADUs.
• Height: Generally up to 16 feet, with some exceptions for two-story ADUs (up to 25 feet in certain zones).
• Parking: No additional parking required in most cases, especially near transit.
• Owner Occupancy: No owner-occupancy requirement until 2025 for most ADUs.

Sacramento Local Requirements

While California state law provides baseline regulations, Sacramento may have additional local requirements. GatherADU's team stays current with Sacramento's specific zoning codes, architectural guidelines, and permit processes to ensure your ADU project meets all requirements.

Common local considerations in Sacramento include:

• Design review requirements and architectural standards
• Utility connection fees and impact fees
• Fire department access requirements
• Neighborhood-specific overlay zones

California law (AB 68, AB 881, SB 9, and subsequent legislation) guarantees your right to build ADUs. Cities cannot:

• Require owner-occupancy for ADUs permitted after 2020
• Require additional parking for ADUs near transit
• Charge impact fees for ADUs under 750 sq ft
• Deny ADUs that meet state minimum standards
• Impose lot coverage limits that prevent a 800 sq ft ADU

If you believe your ADU application is being unfairly denied, California HCD can intervene on your behalf.

Unique Aspects of Sacramento:

Sacramento is known as "America's Farm-to-Fork Capital" due to its proximity to agricultural areas and emphasis on locally sourced cuisine. The city hosts an annual Farm-to-Fork Festival celebrating this aspect of its culture.

The city has a rich history, particularly related to the California Gold Rush. Old Sacramento, a 28-acre National Historic Landmark District, preserves the city's 19th-century character.

Sacramento's climate is Mediterranean, with hot, dry summers and mild winters. This climate supports the region's agricultural productivity and allows for year-round outdoor activities.

The American and Sacramento Rivers converge in Sacramento, providing opportunities for water recreation and contributing to the city's natural beauty. The American River Parkway, a 23-mile stretch of protected land along the river, is a popular spot for cycling, running, and outdoor activities.

Sacramento has been making efforts to become more bicycle-friendly, with an expanding network of bike lanes and trails. The city is also investing in public transportation, including light rail expansion.

The city's diversity is reflected in its numerous cultural festivals, including the Pacific Rim Street Fest and the Sacramento Japanese Film Festival.

In conclusion, Sacramento offers a unique blend of urban amenities, historical significance, and connection to nature. Its ADU regulations reflect the city's commitment to addressing housing needs and increasing density in a sustainable manner. As the city continues to grow and evolve, particularly with an influx of residents from the more expensive Bay Area, ADUs are likely to play an increasingly important role in its housing landscape.
